GEORGE ALLEN, JR., OF NEW YORK, N. Y., AND FRIEDRICH C. SIMPSON, OF WEST SOMERVILLE, MASSACHUSETTS, ASSIGNORS TO GEORGE ALLEN & SON, A FIRM CONSISTING OF JANE ALLEN, WILLIAM ALLEN, AND GEORGE ALLEN, JR., ALL OF NEW YORK, N. Y.

WALL coNsrniio'rIoN.

Application filed May 14, 1927. Serial No. 191,505.

wall to which a single wall extension is to be applied, and itcan be used to particular advantage in connection with the air cooled wall forming the subject matter of our Patent No. 1,674,422, dated June 19, 1928.

The invention embodies in part a series of spaced brackets which can be suspended on one part of the double wall and engaged with the opposite part of said wall, and which will provide means for carrying closing or sealing members to the air space of the double wall, and will also combine conveniently with means for supporting the single wall, the brackets having hanging means which are disposed below their topsso as toleave the space above unobstructed. The invention is intended further to provide means for conveniently and securely supporting the upper extension, and to have the supporting brackets disposed so that any part of the wall can be easily repaired by removing a desired section or part, and a bracket or more if desired without disrupting any great part of the wall. These and other advantages will appear from the description which follows.

Reference is to be had to the accompanying drawings forming a partof this specification, in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a broken sectional elevation of .a double or air cooled wall having a single wall extension at the top and embodying our -invention.

Figure 2 is a sectional plan on the line 2-2 of Figure 1, and

Figure 3 is a broken enlarged perspective showing in detail the bracket elements forming an important part of our invention.

In the drawing we have shown the application of the invention to the type of double wall referred to in our patent hereinabove mentioned, in which 10 represents the outer part of the wall, 11 the inner part, 12 one of the hanging elements of such wall, 13 the hook of the bracket by which it and a section of the wall are suspended. The above is the type of construction referred to 1n our other application, and is especially applicable for the wall of a boiler setting.

Where thelower or double wall is to be extended we employ a series of brackets each having a body or vertical web member 14 preferably in the form of an I beam in section, and this web or body has preferably at the bottom. but at any rate near the bottom. a ledge 15 extending at right angles to the body and adapted at one end to be imbedded in the inner wall 11, and at its opposite end to project into contact with the outer wall 10. These brackets are arranged in spaced relation as shown in the sectional plan in. Figure 2, and the ledges 15 afl'ord means for closing the space between the double wall, the ledges being adapted to carry tiles which extend from ledge to ledge to effect such closure. These are not shown asthey form no part of the present invention.

Each ledge 15 has an opening 16 vertically therethrough, so that the book 13 of one of the hanging elements 12 can extend upwardly through it to engage the flange of a channel iron or similar support 18 on the wall 10. The ledge '15 is slotted from the opening 16 through the outer wall as shown at 17 to facilitate the engagement of the hook 13 or a similar hanger with the support 18, and the ledge is stiffened by a flange 19 which rises vertically around the edge of the opening 16,. the opposite sides of the flange being connected by a bridge 20. After the hook 13 is engaged with the member 18, the flange around the opening 16 is covered as described in the other application above referred to.

Each bracket body 14 has near the upper part and projecting above the ledge 15 and in spaced relation thereto, a hook 21 which instead of projecting above the bodi 11 ot the vbracket as in the lower part of Figure 1. and

and on the web 14 of the bracket, is an abutment 22 which serves to partly close the mouth 21 and hold the bracket in closer relation to the channel iron 18 which supports This channel'iron 18 is suitably supported on the wall Part 10, and it serves to carry an I beam or girder 23, whichin turn supports an inverted channel iron 2i or other similar supportin member.

Thus when the rackets are spaced as desired and suspended from their girders 18 the wall 25 oi tile or brick can be built up upon the ledges 15 and in abutment with the sides of the bracket, and carried upward in the form of a single wall, the part 25 being supported on the member 24 and girder 23. Any mason will understand laying these tile or brick, and it will be seen that if the wall is to be repaired at any point. or some change is to be made in it, or it is desired to open it for any reason, the necessary number of tiles can be taken out. and if desired one or more of the brackets, after which the parts can be restored readily.

At the corners a short channel iron 18" can be place diagonally as shown in Figure 2 to support a bracket, and the opposed tile 25 can be curved as shown to complete the cor.- ner and to engage the bracket.

Thus it will be seen that we have produced a very simple, strong and easily applied means for closing a double wall and supporting a single wall extension thereof.

An extremely valuable feature of the inf. vention resides in the fact that ledges 15 act std support the brick disposed above them.

The weight of this brick is, therefore, taken on the beam 23 and is not transmitted to the brick below. Since the brick used in present day constructions, boiler settings and furnaces, will only support a certain weight without deformation, it will be seen that the construction of this invention provides for any desired height of a wall as the weight of the upper brick is taken off the brick below, thus eliminating any danger of deformation ;\in the brick.

- It will be noted that the arrangement of the air ducts between the inner and outer wall issuch as to air cool the wall supporting brackets, the refractions supported by the same, and the girders. It will be understood that the air cooling may be by forced circula-' tion or. by gravity circulation of air which passes, as will be seen, along-the whole length of the girders.

We claim 1". In a wall construction, the combination with a double wall havinginner and outer parts spaced apart, of a supporting plate on one member of the wall, a bracket imbedded in the other member of the wall, a ledge on the lower part of the bracket imbedded in one part of the wall and abutting with the opposite part of the wall, a hook on the bracket disposed below the bracket top and to engage the supporting plate, and a girder carried by the supporting plate, said girder supporting a portion of said other member of the wall.

v2. In a wall having opposed wall parts, one of said wall parts being elevated above and having a horizontal extension over the other of said wall parts, a hanging element for retainingsaid wall parts in spaced relation and supporting said elevated portion, and means on the other wall part for supporting the hanging element and said horizontal extension.

- 3. In a wall having opposed wall arts, one of said wall parts being elevated above and having a horizontal extension over the other of said wall parts, a hanging element for retaining said wall parts in spaced relation, and means disposed within the space between said wall parts for supporting said horizont.'l extension, said means being engaged by said hanging element to support said elevated portion.

7 4. In a wall having opposed wall parts,

.one of said wall parts being elevated above and having a horizontal. extension over the other of said wall parts, a hanging element for retaining said wall parts in spaced vertical relation", a beam for supporting said horizontal extension in spaced horizontal relation to its opposite wall, and means disposed in the space between said wall parts for supporting said beam, said means being engaged by said hanging element to support said elevated portion.

5. A corner construction for walls comprising a vertical supporting element, and a brick having leg portions in angular relar tion to each other, said brick having a vertical slot to interlock with said supporting member, said leg portions each forming a section of one of the meeting walls having portions formed integrally thereon for interlocking with said meeting walls and preventing lateral displacement of the bricks.
